MGP-WRINGER.

To all whom t may concern.'

VBe it lmown that I, LUTHER C. MCNEAL, a citizen of the UnitedStates, and resident of Rochester, 'in the county of Monroe and State of New York, have invented certain new and useful Improvements in Mop- Wri'ngers, of which the following is a specification.

This invention relates to mop-wringers of the type adapted to be supported upon the side of a pail and actuated by means of a hand-lever.

The general object of the invention is to produce a mop-wringer, of the type in question, which is of simple form and inexpensive construction, but eiiicient in operation.

A more particular object of the invention is to produce a mop-wringer in which the mechanism is, to a certain extent, balanced so that the movements of the hand-lever have a diminished tendency to tilt the wringer on the pail upon which it is mounted. Y n

A. further object of'the invention is to provide a stop of simple and convenient form for limiting the operative movement of the hand-lever, the stop being so constructed that it may be conveniently adjusted in the manufacture of the device.

To the foregoing ends the invention consists in the mop-wringer hereinafter described, as it is defined in the succeeding claims.

members are also provided with downward outer projections or hooks 9, which are hooked over the upper edge of the pail ,to retain the wringer in operative position thereon.

Themop-receiver Vhas a movable back 10 of corrugated sheet-metal, which constitutes a compression-member. Extending from the bottom of this member is a forward projection 11, which constitutes the bottom of the mop-receiver. The back 10 is fixed to depending arms 12 which are pivoted, at their lower ends, on a rod connecting the lower ends of the parts 7 as shown in Figs, 1 and 2, so that the back 10 has a pivoted forward and backward movement between the side-members 6, being thus adapted to compress and wring a mop which is inclosed within the mop-receiver.

The swinging back 10 is actuated by means of a toggle-mechanism comprising two levers 16 and 19, which are connected with the back by means of links 21 pivoted to lugs 22 on the back, these links being connected to the upper and outer ends or arms of the levers 16 and 19. The levers are pivoted uponY a rod 17 which extends from one sidemember to theother, and thus serves not only as a pivotal support but alsoas a brace connecting these side-members. In order that the two levers may swing in unison they are connected by an integral rod 18. This rod f is not, however, coincident with the pivot-al axis of the levers, but is located within and below this axis, so as to connect the lower and inner ends or arms of the levers. This arrangementnot only permits the brace-rod 17 to be conveniently used as a pivot, but it alsohas the valuable function of producing a counterbalancing effect. `When the upper arms of the levers are swung forwardly, the rod 18 is swung rearwardly and vice-versa, so that when the parts come to rest their momentum acts iii-opposite direct-ions, and thus the tendency of the mechanism to tilt the wringer as a whole is substantially reduced.

The mechanism above described is actuated by means of a hand-lever which normally projects upwardly, and which may be of any convenient length. vrl`he lower end of this lever is bolted to an arm 14 which projects upwardly from a lateral extension 15 from the outer end of the lever 16. The lever 16 is of sutlicient length to carry this extension clear of the rear edge of the sidemember 6, as shown in Figs. 1 and A, throughout the operative movement of the mechanism, thus permitting the hand-lever to be connected to the lateral extension outside of the side-member7 so that the handlever can be swung forwardly to substantially horizontal position, as shown in Fig. 4. When this position is reached, however, the lateral extension 15 serves as a stop to limit further movement, by engagement with a portion of the rear edge of the sideinember G. The part 23 of the lateral eXtension which so acts is reduced in diameter, as shown in section in Fig. 3, for convenience in manufacturing the device. It is desirable that the movement be arrested when the toggle-mechanism almost, but not quite, reaches straight-line position, as shown in Fig. 3. Any slight irregularities arising in the manufacture of the several parts of the mechanism may be compensated for in assembling it by filing away more or less of the part 23, this operation being facilitated by the reduced diameter of the part, and thus the exact position in which the mechanism is stopped may be conveniently adjusted.

The counter-balancing action due to the arrangement of the rod 18 and the levers of the above-described mechanism is particularly useful when the hand-lever is returned from operative position to normal position, at the moment when its upward and outward movement terminates. The momentum of the hand-lever, in mop-wringers as ordinarily constructed, has a tendency to tilt the wringer outwardly upon the pail, but in my improved construction this tendency is to a large extent eliminated, thus dispensing with the necessity of means of any kind for iixing the wringer upon the pail, other than the mere engagement of the edge of the pail with the hooked-shaped side-members of the wringer.

The arrangement of the hand-lever upon an extension projecting first laterally and then upwardly from the lever 16, aords a simple and convenient construction by which the hand-lever is brought to a position where it may be operated freely, but without the necessity of carrying a roch-shaft through one of the side-members, as has been the practice in previous constructions where this result was desired. Accordingly, it is not necessary to place the operatingmechanism in position at the time of assembling the parts of the fixed casing of the wringer, but these parts may be entirely assembled and riveted, or otherwise perinanently secured together, and the operatingmechanism may then be iixed in place by simply passing the rod 17 through the sidemembers and the levers and riveting one end of it. This arrangement has the further advantage that the mechanism may be easily removed and replaced, wit-hout dismembering the rest of the wringer, in case of breakage of any of its parts. L

I claim 1. mop-wringer having, in combination, a reciprocating compressing-member, and means for actuating said member comprising two levers pivoted intermediate their ends, links connecting the outer ends of the levers with the compressing-member, and a, rod rigidly connecting the levers to cause them to rock simultaneously on their pivots, said rod being connected with the inner ends of the levers and located eccentrically with respect to their pivotal axes so as to act as a counterweight when the levers are rocked.

2. A mop-wringer having, in combination, a fixed casing comprising side-members and a front, a swinging back constituting a compressing-member, a pair of levers pivoted, respectively, to and within said side-members behind the swinging back, a rod rigidly connecting said levers, links connecting th'el outer ends of the levers with the swinging back, a lateral projection from the outer arm of one lever adapted to swing clear of the edge of the side member during its operative movement but to abut against a portion thereof to act as a stop in the innermost position of the swinging back, and a handlever projecting upwardly from said lateral projection whereby the mechanism may be actuated.

3. A mop-wringer having, in combination, a i'ixed casing comprising side-members and a front-member, a swinging back constituting a compressing-member, a pair of levers pivoted, respectively, to and within said side-members behind the swinging back, a rod rigidly connecting said levers, links connecting the outer ends of the levers iwith the swinging back, a lateral projection from the outer arm of one lever adaptedv to swing clear of the edge of the side-member during its operative movement but having a port-ion, of reduced diameter, adapted to cooperate, with a portion of said edge, as a stop to limit the operative movement of the mechanism, and a handlever, projecting upwardly from said lateral projection, whereby the mechanism may be actuated.
